A Delta Air Lines pilot hit a passenger as she and at least one other woman fought on the floor of a boarding ramp. The incident took place in Atlanta last week, and was recorded on someone’s cell phone. The video circulated around the Internet this weekend and went viral.

The video shows three people cursing at each other before getting physical. One woman takes another woman to the ground, and puts her in a choke hold. At that point, a Delta pilot strikes one of the women. According to SF Gate, it’s unclear whether he does it with an open or closed fist.

In a statement emailed to The Washington Post, Delta spokesperson Brian Kruse said the pilot was trying to de-escalate the fight.

"We became aware of this incident and a video last week and immediately removed the pilot from duty while we completed a thorough investigation," Kruse said. "Local law enforcement was called to respond at the time of the incident. The pilot has since been returned to work as our investigation found that his actions de-escalated an altercation between passengers on the Jetway floor during deplaning."

The women fighting knew each other and also got into a fight while on the plane, according to Crime Online. The women declined pressing charges.
